Jules Andrieu began his career in the early days of photography, when the daguerreotype process was still in its infancy. Andrieu quickly gained recognition for his talent and skill in this new medium and became one of the most sought-after photographers of his time. Andrieu's work is characterised by sharp detail and the use of light and shadow to create dramatic effects. He was renowned for his ability to capture the essence of his subjects, whether they were people, landscapes or still life objects. His photographs are often highly detailed and meticulously composed, with a strong sense of balance and harmony. One of Andrieu's most significant contributions to photography was his use of the daguerreotype process. This process involved creating an image on a highly polished silver plate, producing a unique and highly detailed image that could not be reproduced by any other means. Andrieu was one of the first photographers to master this technique and his daguerreotypes are considered some of the finest examples of this type of photography. Andrieu was a prolific photographer, producing thousands of images throughout his career. He worked in a wide range of genres, including portraiture, landscape, still life and architectural photography. His work was highly regarded by art historians and collectors, and his photographs are held in many major collections around the world. Despite his success as a photographer, Andrieu's life was not without its challenges. He struggled financially throughout his career and was forced to sell many of his photographs to make ends meet. He also suffered from poor health and died in 1876 at the age of 60. Today, Jules Andrieu is remembered as one of the pioneers of photography, and his work continues to inspire and influence photographers around the world. His legacy lives on through his photographs, which remain some of the most beautiful and striking examples of early photography.

Adolphe Block began his career as a photographer in the early 1850s, working with the daguerreotype process. He later switched to the wet collodion process, which allowed him to produce sharper and more detailed images. In 1860, Block opened his own studio in Paris, specialising in portrait photography. He quickly gained a reputation for his ability to capture the personality and character of his subjects, and his clientele included many famous artists, writers and politicians. Block also had a passion for landscape and architectural photography. He travelled extensively throughout France, capturing images of historical monuments, churches and cathedrals. He also photographed the countryside, seascapes and urban scenes. In 1867, Block was awarded a gold medal for his photographic work at the Exposition Universelle in Paris. He remained active in photography until his death in Paris on 25 March 1903. Today, Adolphe Block's photographs are highly sought after by collectors and can be found in many prestigious collections around the world. His work is considered an important part of the history of photography in France.
